TGS has completed extensive reprocessing of 13,550 km of 2D multi-client seismic data located in waters off the Faroe Islands. This project, designated Offshore Faroe Reprocessing 2011, extends across the UK/ Faroe border.

The data was reprocessed using proven sub-basalt imaging techniques already employed on the Atlantic Margin and provides explorers a new insight to the prospectivity of the Faroe Shetland Basin.

TGS has completed the reprocessing of 31,000 km of Baffin Bay 2007, 2008 and 2009 data using innovative techniques already proven in the Atlantic Margin. Together with the Baffin Bay 2010 acquisition, these reprocessed data provide a regional, consistent, high quality dataset for the entire Baffin Bay area to enable interpreters to produce meaningful correlation in these frontier basins.

TGS has completed a new 1,800 km multi-client 2D survey in Northeast Greenland in partnership with Fugro. The BMP has announced the first licensing round for this region which opened 1 January 2012. TGS has produced a fast track processing product which is now available for companies who are exploring this region. The full processed data set will be available by the end of Q1 2012.

The Government of Greenland has confirmed the next licensing round will be carried out in the Greenland Sea in 2012 and 2013.  The pre-round will officially open on 1 January 2012.

The Ministry of Petroleum and Energy (MPE) announced the Norwegian 22nd licensing round on 2 November 2011, comprising blocks over the frontier areas of the Norwegian continental shelf.  Oil companies are invited to nominate blocks by 11 January 2012. APA 2012 has expanded the pre-defined area by a total of 48 blocks or parts of blocks, compared with the area in APA 2011.

The Sierra Leone Petroleum Directorate announced Sierra Leone’s 2011/2012 Petroleum Bid Round for nine blocks totalling 21,242 km².

A fast track glimpse in TGS' first multi-client 3D survey in Gambia’s deep waters. This survey covers 2,500 km² over Gambia blocks A1 and A4. Specialized data processing will be done at TGS’ imaging center in Houston, TX.

The line of the month is from TGS’ Baffin Bay 2010 2D seismic survey, Northwest Greenland.

The line of the month is from the Baffin Bay basins offshore Greenland and Canada. It is located over one of the deepest unexplored arctic sedimentary basins and the line displays very few of the significant four way dip closures seen in the region.

The Line of the Month is from TGS’ Greenland 2009 regional survey in Baffin Bay. This 2D prestack time migration is part of 15,000 km acquired in 2009 in this area.

TGS has an extensive library of 2D and 3D multi-client data offshore Liberia.

 The Line of the Month is a pre-stack time migration from the new Liberia Ultra Deep project. This data extends TGS data into water depths of 4,000 meters offshore Liberia.

Multi-client data available in Madagascar includes seismic, gravity, magnetic, aeromagnetic, well logs and interpretation reports.

The Walvis Basin Survey consists of 9,260 km of 2D seismic data and 4,678 km of gravity data offshore Namibia. This program covers open acreage and compliments TGS’ exisiting 25,000 km of Namibia multi-client data.

TGS' Faroe Shetland Basin surveys identify a number of possible hydrocarbon plays in designated and undesignated areas. 

This is an example from TGS’ North Sea Renaissance 2009 long offset survey West of Shetlands. It is over 135 km long and was acquired using a deep tow to enhance the image the sub-basalt section.

TGS-NOPEC's North Sea Renaissance program (NSR03) will provide long offset data that will cover the entire North Sea Basin on a regular grid.

TGS' line of the month is from the North Sea Renaissance long offset 2D program.

This Line of the Month is from TGS’ worldwide geophysical database and is one of the modern 2D 8km long offset lines from the North Sea Renaissance Survey (NSR). The NSR survey is now in its seventh season and we expect to have over 100,000 km of data available by Q4, 2009. This line is located in the Northern North Sea and has been designed to image the complete basin. Latest data imaging technologies have been implemented including SRME.

The line of the month is a composite line from the Northeast Greenland 2008 survey (NEG08) and the AWI 2003 survey, which was reprocessed by TGS in 2010 (AWI03-RE10).

The Northwest Africa Atlantic Margin program is a joint venture between TGS and Dolphin Geophysical Ltd. The 2D multi-client program includes seismic, gravity and magnetic data located offshore Senegal, in the Gambia, Guinea Bissau, Guinea and the AGC area. The data extends from the Mesozoic shelf to approximately 3,000 m water depth.

TGS is pleased to announce the availability of a fast track data set from the newly acquired 2D multi-client survey in Northwest Africa, acquired in conjunction with Dolphin Geophysical.  

The survey, which is still in the acquisition phase, will total 20,000 km of long offset seismic data in the offshore areas of multiple countries and will improve the understanding of highly prospective areas along the Northwest African Atlantic Margin. 

The line of the month is from TGS’ Hoop Fault Complex multi-client 3D survey in the Norwegian Barents Sea.

The line of the month is from TGS’ Hoop Fault Complex multi-client 3D survey (HFC09) in the Norwegian Barents Sea.

The line of the month is from TGS’ Hoop Fault Complex multi-client 3D survey in the Norwegian Barents Sea.

The Report has identified extensive stratigraphic trapping mechanisms in the Tertiary, structural/stratigraphic traps in the Cretaceous, established source rocks and proven petroleum systems.

This seismic line in an East-West direction is from the TGS-NOPEC survey KFW98 in the Norwegian Sea. The area is on the Tertiary inversion between The Ormen Lange Gas Field and the Helland Hansen Dome.

The Rås Basin and in particular the Cretaceous interval is a challenging task due to its severe noise problems. The bright set of reflectors in the centre left part of the line below is a sand prone interval (Lysing Sand). This is hardly visible on the original data or any other data from the same area.

Offshore Liberia is a vast unexplored region covering more than 100,000 km² - to water depths of 4,000 m. There were only 7 exploration wells drilled offshore from 1970 to 1985.

The Line of the Month is a prestack time migration from a TGS 2D survey off the coast of Liberia. Offshore Liberia is receiving significant interest, due to new oil discoveries in the region. TGS has 14,000 km of multi-client 2D data here.

The line is showing salt related structures in the Upper Jurassic-Cretaceous succession unconformably overlain by a Tertiary-Recent succession. A thick Lower-Middle Jurassic section, predicted to contain the main potential source rock interval in the Algarve Basin, is present below the Upper Jurassic salt.

The Northern Red Sea area hosts a classic triple junction of the Red Sea, Gulf of Aqaba, and Gulf of Suez rifted basins. The sedimentary succession here can be divided into prerift (pre-Miocene) and synrift (Miocene and post-Miocene) megasequences.

TGS-NOPEC has recently completed processing on its first major multi client 3D survey in the UK. The East Shetland Basin Survey (ESB-MC-3D) covers almost 1,000 sq km of licensed and open acreage, the majority of which is included in the UK 20th Licensing Round.

TGS has recently completed processing of new multi-client 3D high density data in the UK North Sea. The 2010 Moray Firth survey (MF10) provides a significant upgrade on previous data in the area. 

This is an example of a dip line from TGS’ East Shetland Basin survey (ESB09), a joint TGS/PGS venture.

This Line of the Month is from TGS’ West Africa Regional survey offshore Ghana. This 2D prestack time migration is part of the 9,800 km acquired for this project.
